Possible solutions:
- Paralyze my schedule such that nothing is planned and everything becomes "spontaneous" (downside: yeah, that never works, I wind up watching too many re-runs of old movies).
- find some way of shortening my planning horizion to 12 -24 hours (This doesn't work with Cycling with friends, or with biking into work, or any of a number of events that require more than 12 hours of planning).
